A photo in a tweet from Uber employee Chenyu Zheng yesterday appears to show a cake decorated with a WeChat logo, and an arrow pointing to a Facebook logo. Below the cake is Grover’s name and a sign that says happy birthday.

“Silicon Valley is trying to learn from the success of Asian messenger apps,” states Grover in a recent essay. “This involves a peculiar fixation on how these apps, particularly WeChat, incorporate all sorts of functionality seemingly unrelated to messaging.”

It is unclear at this stage what role Grover will assume at Facebook. In the past, he has written extensively about messaging apps, and bots, on his blog.
